This week the teaching seminar will have two parts:
1) Low floor / high ceiling mathematical tasks. In other words, problems that are easy to get into, but allow a lot of scope for deep thinking.
My current favorite is one I've used at the beginning of Calc III, and also at the beginning of the 3D / vectors / lines & planes part of Calc II: Let f(t) = (t-1,3-t). Sketch the points f(0), f(1), f(2), f(3), and f(4) in the plane. What do you notice?
What problems have you used that have a low floor and a high ceiling? How could we lower the floor, or raise the ceiling, on tasks we ask our students to do?
2) If time permits, discussion of the article "What Does Active Learning Mean for Mathematicians?" which appeared in the February Notices of the AMS. Thanks to Peter Andre for pointing it out to me!

In this seminar I will talk about my use of voting questions in my SM221 class this semester. I was encouraged to start asking voting questions from a Project Next Seminar at the MAA MathFest in 2016. In the seminar I will give an example of a voting type question. I will also discuss some research behind voting questions, and give resources that you can use in your classes.
